Cleaning is made easy with tile. While a shower is used daily, the opportunity for mold and mildew is possible but tile is easily cleaned with normal household products and doesn't need special cleaners to maintain.
Showers can be a challenge for one to attempt on their own because of risk involved with containing the water. Mold and rotting wood can cause permanent damage to your home. I have specialized in using the Shluter brand of products. They have an effective and proven system to ensure water control.
